internet speed upgrade to 400mps from 100mps at Xfinity

[marialey]

I just upgrade the internet speed from 100mps to 400mps through xfinity by promotion.  Do I need to do anything on the wifi cable modem router in order to obtain that speed?  When I do the speed test now, I don't see any difference after upgrade.

At the end, the problem is from Xfinity.  They just didn't upgrade my account correctly.  So after I called Xfinity, the speed is upgraded to around 400mps from their website speed test.  I don't need to do anything at my end about the modem.

What router do you have? 

What speeds do you get if you speedtest over a hardwired connection (not wireless)?

I have Nighthawk AC1900 WiFi cable modem router model C7000v2.  I still have around 100mps from speedtest through ethernet connection to my computer, instead of what the provider provides 400mps.  Thanks.

What computer is it? 

Does it have a gigabit ethernet port or only a 10/100mbps port? 

Have you tried a different device? 

Have you tried a factory reset and reinstall?
